What to do if the vehicle fails the OBD test during inspection?

[LukasRose]

The solution for a vehicle failing the OBD test during inspection is: Visit a 4S repair shop to troubleshoot and clear the fault codes, or have the vehicle system upgraded at a 4S shop before reattempting the inspection. Below is relevant information: 1. Annual inspection items include: Checking whether the vehicle has been modified, altered, or reconstructed; verifying if the vehicle registration, license plate, and all records in the vehicle file match the actual condition; and ensuring the vehicle's braking system, lights, emissions, and other safety performance meet regulatory requirements. 2. Circumstances under which a vehicle cannot undergo inspection include: Discrepancies between the vehicle's condition and the records in the driving license or file; damaged, incomplete, or illegible license plates or driving licenses, or self-made license plates; vehicles that have undergone modifications, alterations, or technical transformations without proper approval and modification procedures; and vehicles that have not been marked with the required unit name and enlarged license plate characters.
